Yeah, it's a nogo at this time. There are custom roms that allow otg + charging so it could be implemented in a future update. The powered hubs don't send voltage down the host cable.

I use a nas drive to stream media over wifi, it works while charging. If your router has a usb port, try plugging a flash or hard drive in it. Then use a file explorer to stream or copy. Or from another computer on the same wifi set to share folders with the network.

Your widrive is portable battery powered. Pogo will keep from straining the usb jack. Should see it soon, but for 50$ they better include the charger.My uverse router doesn't have usb, check yours. An ethernet hard drive box would be cool, but would need some file server rom.
